Multi-Wavelength Abbe Refractometer DR-M4/1550 [7650-01][MICROLAB] 000ug/mL SELENIUM 125mLRefractive index or Abbe number (d or e) can be measured at different wavelengths ranging from 450 to 1,550nm. This refractometer digitallys display measurement result of refractive index or Abbe number on the LCD. This measurement can be achieved by matching the boundary line with the intersection point of the cross hairs This is connectable with Digital printer DP AD(B) (Optional).
